Ok, i had a very similar issue after i updated from Big Sur to Monterey and it was even worse, nearly all the sites were eventually crashing, especially if there was a video content. Finally solved it by going to the official orion site and downloading a version of orion specifically for Monterey(there are different links for different OS versions)
Maybe will help someone. It was strange, because the updater indicated that i'm up to date. Probably it was up to date on Big Sur "branch"
